However, she said police are not linking this to the investigation, adding that neither her son nor April had anything to be ashamed of.

"Corrie and April were on dating sites, they are young and were enjoying themselves," wrote Nicola, herself a police officer. "They were both seeing other people, this has not been hidden."

Nicola continued: "April and Corrie had a fab swingers account, to the haters, get over it. This is none of your business, April could have easily deleted her account as I could have deleted Corrie's however what was far more important than a little embarrassment was that the police were informed immediately and given every ability to ensure this did not have anything to do with Corrie's disappearance. Which they are still doing."

A Suffolk Police spokesman said: "Police are aware of the social media and websites Corrie was using and this is part of our investigation. We will not be commenting further at this time."
